VSDC Video Editor is currently freeware as a beta release for Windows. It includes very good and easy "chroma key" "green screen" editing capability. VSDC Video Editor is currently freeware as a beta release. It's currently one of the few freeware programs that has "chroma key" editing capability. Now you too can make videos like freddiew! I'm aware of only two other freeware programs with chroma key capability (Debugmode WAX and Zwei-Stein), and both are difficult to use as compared to VSDC. Additionally, with VSDC you can edit and save in most popular video formats and compression schemes including high definition (HD), AVI, H.264, MP4, MKV, MTS, 3GP, WMV, QT, MP3, MPEG2 FLV, SWF. YouTube. Get it now while it's free because eventually this will go payware.
